It's a reasonable question.  I don't feel strongly about it, but I
prefer lock-free programming where practical, and in this case there's
really no need for coordination between threads.  Indeed, these UUIDs
are already designed to avoid collisions between multiple _sessions_
without coordination.  So why bother with the lock?
